Improvements on Higher Order Ambisonics Reproduction in the Spherical Harmonics Domain Under Real-time Constraints

Efficient auralization techniques are gaining immense importance through new generation 3D Audio systems aimed at gaming and mixed reality scenarios. A powerful and flexible rendering approach is describing the spatial sound scene in spherical harmonics or Ambisonics. However, limiting the reproduction accuracy in order to improve performance introduces severe coloration of the audio signal. We propose two strategies to improve on binaural playback for higher order Ambisonics. The proposed approaches increase perceived Audio quality without requiring any additional real-time processing.

Christoph Hold studies M.Sc. in audio communication technology and holds a B.Sc. in electrical engineering from the Technische Universität Berlin, where he specializes in signal processing and virtual acoustics. He is interested in high quality audio and its perception. As a mix engineer and musician, he is concerned about the underlying technology—from recording and processing music to the final listening experience. From 2015 to 2017 he was a research assistant at TU Berlin, followed by a first research internship at Microsoft Research in Redmond, WA, USA.
